HVIPRQVEMENT iN PLOW-CLEVISES.

Specification forming part of Letters 'Patent No. 137,'7'S, dated March25, 1873.

To all whom 'it may concern:

Be it known that I, AUGUST KAUFMAN, of Davisville, Yolo County, State ofCalifornia, have invented an Improved Plow-Clevis and I do herebydeclare the following description and accompanying drawing aresufficient to enable any person skilled in the art or science to whichit most nearly appertains to make and use my said invention orimprovement without further invention or experiment.

`My invention relates to an improved elevis by which thezdirection oidraft can be shifted readily without stopping the team.

In order to more fully illustrate and explain my invention reference ishad to the accompanying drawing forming a part of this speciiieation, inwhich- Figure 1 is a perspective view o the plowframe and elevis.

A B O are three parallel plates or bars of metal ofthe desired strength.rIlhe two bars A B form the supporting-beams to which the plows D E aresecured, and the other on C forming an outside support for the wheel F.The metal beam A forms the inner side of the l plow-frame, and itsforward end is bent at the front end I of which is bent t0 a U sha-pe soas to clasp the draftbar above and below, in which position it issecured by a bolt passing through the rod and draft-bar. The rear endofthe bar o is bent upward so as to pass above the rack m, and form alever by which the position of the elevis can be changed. By shiftingthe lever in either direction along the rack the elevis will be given anopposite direction or draw so as to give the plow more or less land, asdesired, and this can be done without stopping the team.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The elevis o, with its lever-handle c, in cornbination with the rack m,substantiallyas and for the purpose described.

In witness whereof I hereunto set my hand and seal.
